variable ratio reinforcement

The single best method of reinforcement from a learning theory standpoint is a variable ratio schedule of reinforcement. That is to say, one will receive a positive reinforcer (a consequence that increases the likelihood of future specific actions) after a variable number of target bahaviors. Unlike a fixed ratio, the variable ratio is unknowable by the learner. The most notable example is a slot machine. Other examples include clicking to this blog over and over and over knowing that one of these clicks something good is going to show up. Just remember that the odds always favor the casino!
